OPHTHALMIC MOUNTING.

Application filed December 18, 1920, Serial No. 480,128. Renewed July 29, 19M.

The present invention relates to ophthalsion 4 at one side formed of non-metallic mic mountings and an object thereof is to material and provided with a bevelled end provide an improved connection between the temples and the lens frames, particularly in t at type of mounting in which the temples and the lens frames are formed from non-metallic material such as zylonite, celluloid or the like. A further object of this in-' vention is to provide in an ophthalmic mounting having the lens frames and temples formed of non-metallic material, a metallic hinge which will be strong and durable "in use and at the same time will be so mountnon-metallic frame which will strengthen these parts adjacent the hinge. Another and still further object of the invention is to provide a reinforcing piece for the temple pivoting extension of a non-metallic lens framewhich will act as a lock for preventing the turning of the lens.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims. a

In the drawings:

Fig; 1 is a plan view of a fragment of an ophthalmic 4 mounting adjacent one of the lens frames and one of the temples;

Fig. '2 is a horizontal section of the parts shown .in- Fig. 1

Fig. 3 is a vertical section through a fragment of-a lens frame and its extension showing the manner in which the metal reinforcingliiece locks the lens against turning; and

1g. 4 is a sectional viewshowing the man her in which the temple end is reinforced by the means forpivotally securing such temple to the lens frame.

Referrin more articularly to the drawin 1 in icates the lens frame, of which 0 y a fragment is shown, having a lens rec i g coived; e frame 1. hasan'integra1 extenoove2 in which the lens. 3. is rehaving its inner end projectin at 7 into the groove 2 so as to enter a note 8 formed in the lens3 for the purpose of'preventing the turning of the lens in the lens frame especially where the frame and the lens are both of circular form. This reinforcing piece 6 preferably has prongs 9 on opposite sides extendmg toward the outer end of the reinforcing p ece.v At its outer end this reinforcing piece may be provided with one or more ears 10 formed with aligned perforations 11, flat surfaces 12 being provided on the reinforcing pieces between and on opposite sides of the two cars 10 so as to form an abutment for.

liiniting the outward movement of the tem- The temple 13 has, in this instance, its hinged end made of non-metallic material such as zylonite, celluloid, or the like .and has its end bevelled at 14 so as to cooperate with the bevelled portion5 on the frame extension 4 and provide a closed joint between these parts when the temple is in open position. The temple may also be reinforced by an insert or reinforcing piece 15 havin prongs 16 on opposite sides extending towar the pivoted end of the temple. At its outer end the temple may be provided with one e or more ears l7 extendin inwardly from the reinforcing piece 5 and aving abutting surfaces 18 between them. The ears 17 have aligned openings and a pivot pin 19 passes through these ali ed openings and the aligned o enings o the ears 10 to pivotally connect t e temple to the lens, frame. side of each of the ears 17 is flattened at 20 to cooperate with the abutments 12 on the reinforcing piece 6, while one side of each of the ears 10 is flattened at 21 to cooperate 1 with the abutments 18 onthe reinforcing piece .15. 7

From the foregoing it will be seen that there has been provided an ophthalmic mounting in, which the lens frames 'andtem- 'ples are made of non-metallic "material and are connected by a hinge or pivot whidi has anchorin portions extending into the temple and t e frame extension in such a manner as toreinforce' these parts adjacent the One hinge where most of the strain occurs. The

' hinge is invisible from the front and the sides of the mounting and permits the non metallic arts of the temples and frames to be broug 1; into abutment without placing any strain on the abutting ortions of the arts due to the fact that t e hinge memrs areprovided with abutting portions. The member of the hinge which is secured in the frame extension may, project into the lens groove and act as a lens lock for preventing the turning of the lens in the frame.

What I claim as m invention and to secure by Letters atent is: L

1. An 0 hthalmic mounting comprising a non-metal 1c lens frame havin a nonmetallic extension at one side, sai extension being provided with a bevelled end ortion, a temple having a bevelled non-meta lic end portion, and a hinged connection between the temple and the extension, permitting the bevelled portions to abut and embodying two desire .pivotally connected metallic members se-' cured to the frame and the temple and I 'having abutting portions-cooperating, when the abutting portions on the temple and extension cooperate, for the pur ose of limiting the outward movement of t e temple.

2. An 0 hthalmic mounting comprising a non-metal ic lens. frame provided with a lens groove and having 'a non-metallic extension.

at one side thereof, a reinforcing piece extending through the extension and lnto said gnoove to act as a lens lock.

o hthahnic mountin comprising a non-meta ic lens frame provi ed with a lens groove and having a non-metallic extension at one'side thereof, a reinforcing piece ex-' tending through the extension and into said lensgroove to act as a lens lock, and a temple pivotally connected to said reinforcing piece.

4. In a non-metallic spectacle frame, rims, carriers on the rims provided with grooves in their ends, and metallic members comprising shanks embedded in the carriers, and

knuckles and a hinge rings on the shanks registering in the grooves.

5. An 0 hthalmic mounting com rising a non-meta 1c lens frame formed wit an extension at one side bevelled at its end, a

temple having. an inner end. bevelled and formed of non-metallic material to cooperate with the bevel on the extension of the lens frame, and a hinged connection between the temple and "the extension embodgin two members, each having a portion em d edin one of the first two named parts and a portion pivotally connected to a like portion on the other member in the connection, such ortion on the lens frame member projecting rearwardly from. the extension adjacent the bevel of .the latter and such portion on the temple member extending rearwardly from the temple adjacent the bevel on the temple.

of a bin e 'oint-for connecting the temple bars to t e ens frames, comprisin socketed portions in the confronting en of the temple bar and lensframe for res ,ively receiving and concealing the bin eeaves.

7. In a spectacle frame inc uding lens rims, temple bars and a hinged connection 'therebetween, socketed portions formed iny with recesses extend-' 'et 6. The combination in a spectacle frame,

for receiving and concealing the hinge leaves.
